Hi,

I'm installing a recessed light in my soon-to-be enclosed boiler room. The boiler room will have 5/8" thick fire rated drywall ceiling and walls. Here's my question:
Do I need a special fire-rated recessed light can?
Do I need to make a 5/8" drywall box all around the light, in between the ceiling joists?
Or do I just use any standard recessed light can and move along with my work?
What is the right thing to do?

Thanks,
Theodore

The ceiling can lights would be my choice. Keeping any heat from
possibly causing a fire in the space above, in case something goes
wrong in the light. YMMV.

He already said light cans, just wanted to know if they should be fire
rated.

You need to maintain the fire rating of the ceiling. If the AHJ is OK
with your "fire rated" lights, you are done.
I have seen the boxes tho.

Progress makes fire rated recessed lights. Go to a lighting store or an electrical supply for price and availability.

Check with your buiding inspector and fire inspector to see if a fire rated can is required.

Just installed 8 can lights, Portland, OR. Had to build 5/8 drywall boxes, and when done, had to use fire-proof caulk on all the wire penetrations. Floor (basement ceiling) joists were uniformly spaced and I precut all 40 pieces. Pain in the a** but doable in circa 2 hours.

Pain in the a** indeed.

I gave up and pulled out the recessed light and put in a traditional ceiling box. So, my boiler room will have a good ole' fashion light fixture.

Thanks so much to all the respondants for your technical insight.

I think that was the smartest thing to do. Simple, inexpensive, solution
and no issues about the fire rated ceiling.
